At the time 7D users and, more importantly, potential 7D buyers were getting anxious about when a 7D Mark II might be released. Replacement rumors had been flying for a while. Then rumors began to swirl that Canon was having serious development issues with the sensor. The usual grumbling began about "jumping to

Canon claimed it increased from 14 to 25 raw images with UDMA-7 CF cards, but most independent testers said it increased to around 31-32 frames before the buffer bogged down with the fastest CF cards.
